MILWAUKEE – Skylar Diggins scored 23 points and Natalie Achonwa added 17 points and 10 rebounds as No. 2 Notre Dame rolled to its 19th consecutive victory with a 87-49 rout of Marquette on Sunday.

The Irish (24-1, 12-0 Big East) have won a school record 20 consecutive regular-season road victories, including 16 straight in the conference.

Notre Dame's lone loss of the season was to No. 1 Baylor 71-63 on Dec. 5.

The Irish led by 19 at halftime and put the game away early in the second half as Notre Dame scored the first 12 points of the half to grab a 46-15 lead when Diggins scored on a layup. Diggins was the key to the spurt as she scored six points, including a steal and breakway layup.

Marquette could get no closer than 24 points the rest of the way.

Sarina Simmons scored 12 points and Arlesia Morse added 11 for Marquette (12-13, 4-8).
